Describe the bug
I'm using vim-fugitive plugin, so when i use :Gdiff command in a file that was changed, coc.nvim opens vertical split with the following error

[Info  - 18:04:27] ESLint library loaded from: /home/maz/server/www/homestead/voice-mvp/node_modules/eslint/lib/api.js
[Error - 18:04:37] ESLint stack trace:

It's because eslint module is not found, there is

  "eslint.packageManager": "npm",

in settings.json to make it same as VSCode's settings.json, you can either run

npm i -g eslint

or if have installed eslint with yarn, add:

 "eslint.packageManager": "yarn",

to your coc-settings.json

The error is confusing, it could be improved.

I already have eslint installed globally

[chemzqm]

The eslint server check the folder: npm root -g, not the executable file.

[deathmaz]

ok, i tried your suggestions from #32 (comment), but i still have the error

[chemzqm]

Add

"eslint.enable": false

to disable eslint for now, I will send a fix for this.
